“Party in the U.S.A.” became Cyrus’ best charting effort to date on the Billboard Hot 100 and her fifth U.S. airplay hit.

Released as the lead single from Cyrus’ second extended play The Time of Our Lives, it served as promotion for her Wal-Mart clothes line with Max Azria.

Jocelyn Vena of MTV, described the video as “reminiscent of Cyrus’ performance of the track on the Teen Choice Awards over the summer – minus the pole dancing.”
